To mit 101mm, it may oon-cern.- l Be at known that I, CHARLES JOHNSON, a

4citizen of the United States, and. a resident of -And'to that end the invention consists in the novel construction and combination of the component parts of the mechanisms hereinafter described and claimed.

In the accompanying drawings Figure l is a side elevation of a. lnanurefspreading inachine embodying my invention, showing the endfboardin. its raiseddposition; Fig. 2 is elevation of the o posits side of the machine showin the endo'ard in its lowered posi-Y Y tion* ig. 3 is a transverse section on the line; xfs-n Fi l. Figs. 4 and 5 are face views ofJ 'the aw and ratchet, which transmit motion, om the traction-Wheel to the niecnansms which impart motion to the apron shaft, Fig; 6 is an enlarged fragmentary side view of part of the devices for :throwing the beater-driving mechan ism in and out 'of gear; Fig. 7 is a transverse section onthe line -2- z in Fig. 6; Fig` 8 is a transverse section on the line -Jy-yin Fig. 6; and Fig. 9 is a face view of the Vpawl and ratchet which transmit motion from the traction-.Wheel to the beater-actuat' mechanism.

' 1.- denotes the odyor box of the vehicle v in which the manure is transported to the field u on which t e inannigey is to be distributed. T e bottom o `,saidbody consists cfa longi'y tudinally movable apron -2- composed of transverse slats attached to endless chains which are carried on sprocket-wheels --3---4-m mounted on transverse shafts -5-6 near the front and rear ends of the body -1. The `Wheels are fastened to the rear shaft n--6- journaled in suitable bearings attached to the body. Said rear shaft receivesrotary motion by means of suitable mechan-V ism, which does notpertain to my present invention and is only partly shown in Figs. 2, 4

traction-wheeljee Figs. 4 and 5).

and 5 of the drawings, in which 17' denotes av axle -10- of the traction-Wheel --9-- and receives motion by means of a suitable clutch or by paivls -1Supivoted on a spider .W1 9ifastened to the disk-gear -174- and engag ing a ratchet gF20-i in the hub -2 1 of the A shaft 265- Vsiwrr'n Fig. 2 receives rotary mo tion from the disksgear w--17- and has rigidly attached te it a worm -0 which engages a Worm-gear attached to the apronshaft m6?. The apron 2- thns receives longitudinal movement. -,-3 2- re resents a collar connected to suitable s eed-c Vengi devices mounted 4on the sha t 26- an provided with eersI 34, to which is connected the rear end of a rod -35, the front end of which is connected to a lever *62+ "by ineens of which the speed-changing de-l -`-7' represents the-11's' al beater, which extends across the rear end of the machine" and has its shaft -8- jonrneed in suitable bearings securedV to tbesdes oiV the body -Q-Q- are the traction-Wheels which are journaled on the hind axle iO- 1frepresents the end-board which is movable vertically and placed across the disk-.gear which is mounted loosely on the l interior of tliebodyA-lat a short distance from the fronte the beater 4during the tienev of loading the manure in the body ,--1-i-V and conveying it to the field, thus preventing the mannre from clogging the beater. Theendboard being subsequently raised to allow the manure to pass te thebeater svhichscatters the manure nnen the field" traversed" by the machine. Said end-board is attached at its toptea shaft 12 by which it is suspended from arms -13 ivoted to the exterior of the sides of the bo y --1`-j Said arms are *formed with inwardly projecting tubular bearings *i4-- into which the en ds of the shaft -12- are inserted, These bearings corne in contact with the top of the body *when the end-board is lowered into the body end tlnis limit the descent of the endboard. To the front end of the body is piv- Yoted a hand-lever' 15-M Wliich is connected with one of the arms -13 by a rod -16-. Seid handlever and its connections allows IOS IIO

the attendant of the machine to lift thc endboard when the machine is set into operation.

The beater 7m receives rotary motion from mechanisms actuated by the tractionwheel `Q- adjacent to the inner side of which is a gear-Wheel 38H mounted loosely on the axle ---10 and rotated in one direction'by pawls H39* pivoted on pins 40- projecting from the side of the gear-wheel -38--, which pawls engage a ratchet --41 in the hub of the traction-Wheel as shown in Fig. 9.

To the side of the body "--1- is firmly attached a bracket 421* the bottoni of which is formed with a sleeve -43- re* ceiving throu h it the axle `10- and serving as one of t e supports for the body -1` as shown in Figs. 7 and 8. The outer side of the bracket `A2` has projecting from it two pins or studs -44-A and `45- arranUed one above the other. On the lower stud` --et5- is pivoted an eccentric -46- and 'onthe face of the bracket lies a plate 47- the upper end of which is provided with a Vslot -48-- which receives the upper stud *44 The lower end of said plate is formed .with a circular aperture --49 receiving the eccentric `46fwhich is provided with a radial arn1\50-,' to the end of which is connected the rear end of a manually operated rod -51. This rod is composed of two end sections connected at their junction to an arm -52 pivoted to a plate -53 attached to the body. The front section of the rod -51- is extended and connected to the hand-lever -15 hereinbefore mentioned to allow said hand-lever to control simultaneously the 'end-board `11- and the actuating mechanism of the beater. The rear end-section of the rod 51- passes under the axle l0 and is connected to the arm --vof the eccentric 46.

The central portion of Vthe plate --47- is provided with an outwardly projecting stubshaft `54 on which is journaled a pinion -55adapted to engage the gear-wheel --38-. To the hub of the said pinion is fastened a sprocketvwheel -56-- which is connected by a sprocket chain -58- with a sprocket-wheel attached to the beater-shaft --8--.

The beater is set in .motion and the endboard-11---is simultaneously lifted by the operator throwing thehandlever-15 ina dn'ection which causes the rod 51- to turn the eccentric -46 solas to ush the plate -47- toward the gear-Wheel)1-38- and cause the ini(` '55- to engage said wheel and recelve ro. Airy motion therefrom. The sprocket-wheel `56h rotating with the pinion imparts rotarymotion to the s rocketwheel -57- dn the beater-shaft. ben itis desired to arrest the motion ol' the beater, the operator throws the hand-lever --l 5 in a direction reverse from that before mentioned and thereby causes the rod H51` to turn the eccentric --46- so as to push the plate -47- from the gear-wheel -3- and thus throw the pinion out of engagement with the gear-wheel. Said pinion beingr thereby deprived of motion renders the beater stationary. At the same time the end-board -11` is lowered by the rod 16- connecting the lever-15 to' one of the arms -13- which carry the said endboard. y

lVhat I claim as my invention is 1. A beater-actuating mechanism comprising a gear-wheel receiving motion from the traction-wheel, an elongated plate otally supported at oneend and shiftable longitudinally on its support, a pinion pivoted on said late, means for swinging and shiftingr the plate to carry the )inion to and from engagement with the a'oresaid gearwheel, and means for transmitting motion from the pinion to the beater as set forth.

2. A beater-actuatingr mechanism coniprising a gear-wheel receiving motion from the traction-wheel, an elongated plate pivotally supported at one end and shiftable longitudinally on its support. a pinion pivoted on said plate, an eccentric imparting` a swinging and longitudinal movement Vto the plate to carry the pinion to and from engagement with the aforesaid .gear-wheel, and means for transmitting motion from the pinion to the beater as set forth.

3. The combination, with the bod of arms pivoted at one end to the sides ollysaid body and formed at their free ends with inwardly projecting bearings disposed to contact with the top of the body and thereby limit the descent of the arms, the end-board suspended from said arms, a hand-lever pivoted to the 'body and a rod connecting said hand-lever to the central portion of one of the aforesaid arms.

, 4. A beater-actuating niechansim comprisingr a `fear-wheel receivingr motion from the tractioirwlieel, a stationary bracket, an elongated plate pivoted at one end on said bracket and movable longitudinally on its pivot, an eccentric pivoted to the bracket and imparting lateral and longitudinal movement to the plate, a pinion pivoted to the plate and carried thereby to and from engagement with the aforesaid geanwhecl, an arm extending from the eccentric, a rod connected to said arm7 and a hand-lever ccnnecled to said rod as set forth.
